IMnRovEn HINGE ron sumas.

The Schedule referred to in LetteraPatent and making paxt of the name.

To all' whom it may concern:

Be it known that I, TYLER G. LORD, of Chicago, iu the county of Cook, and 'State of Illinois, have invented a new and useful Improved Hinge for `Win dow-Blinds, and I do hereby declare' the 'following to be a full, clear, and exact description of-'the sauie,

reference being had to the accompanying drawings,

and,` the Aletters and figures marked thereon, which fonn a part of this specification, and in which- Figure 1 represents an -iuside View of the windowblind and casing to which the hinge is attached;

Figure 2, an outsideview of the casing and blind, with the hinge attached;

Figure 3, a top view of the same;

Figure 4, a bottom view; and

Figure 5, an edge view.

The nature of my invention consists in constructing a window-blind hinge, with a circularplate, B, revolving on a central pin, I), and Iprovided with' cogs or teeth C ou the under side thereof, and a cover or projecting rim', F,iu combination' with the bevel-wheel H and shaft I..

To enable those skilled in the artto understand howr to ma'nufactu'reand use my invention, I will describe the same with particularity.

The same letters of reference refer to `the corresponding parts in the different figures.

In the annexed drawing- A represents that part of the hinge that is attached to the window-blind; and

on outside ofthe window-casing There is also a lip or cover, F, extending down from the edge of the plate B below the cogs O, s ,o as to pro,-

tect them from snow, ice, and dust.

H is a bevel cog-wheel, firmly attached to the shaft I, that extends through the window-casing from the inside of the house, there being a knob, J, on the inner end of said shaft, by which it is turned, as hereafter described.

' There is a toothed circular plate, K, firmly attached to the shaft I, just inside of the window-casing, and also a pawl, L, hung to the window-casing in such av position that it will swing down and engage with the teeth of the-plate K, andhold the plate and its shaft I from turning, when desired. I

-'The bevel-wheel His se arranged that it engages with the cogs G on the under side of the circular plate B, so that, when the shaft I is turned, the plate B is revolved' on its central pin I), and opens `or closes' the' blind S. l l

v The shaft I is turned bya person taking hold'pof thel knob J, and when it has been turned, and the blind swung to the desired position, the' pawl L is swung down so as to engage with the teeth of the plate K, and holds the shaft I from turning, and thereby'loclrs the blind. A

Myhinge can be attached to any blind and windowcasing, by simply'boring a hole through the casing for the shaft I, and by the construction ofthe hinge with the large circular plate B, there is a leverage obtained which causes the blinds to be more easily swung.

By placing the cogs O on the under side of the plate l B, and using the lip or coverF, the gearing of the hinge is so protected that it will keep clear of snow,

ice, and dus'tfthat would Otherwise be apt to clog it, and interfere wit-h its operating.

By `using the shaft I and its Aattachment in connection with the hinge, the blind can be Opened, or closed and locked, in any desired position, from the inside of the house, without opening the window.

Having thus Ifully described' the construction and' operation of my improved hinge,

What I claim, and desire to secure by Letters Patent, is

When forming a part of a' Window-blind hinge, the circularl plate B, when provided with a central pivoting-pin, D,vcogs or teeth C, and lip or ange'F, in combination with the support E and bevel-wheel H, when all are constructed and arranged si/ibstantially as IVitnesses:
